Here's what's shown on my 502a and my 502b transformers:
302/502a
2 – 110V Primary windings
2 – 6.3V, 4A Secondary windings with taps at 5V
1 – 6.3V, 3.5A Secondary winding
1 – 70V, 100mA Secondary winding
1 – 370V, 500mA Secondary winding with taps at 10V and 350V
302/502b
2 – 115V Primary windings
2 – 6.3V, 4A Secondary windings

Hi Ronald, thank you for your last email, sorry for the late reply, but with one thing and another it's been quite busy here. Thanks for the measurements. Well once I can get a transformer made up I can start a build of my own. Again many thanks for your help. Regards Ian .
